SynthRotek 1U Unity Gain Mixer Module (black faceplate) (synth module)
Cat: 777893 Rel: 22 Jan 21
mixer module
Notes: The 1U Unity Gain Mixer adds input signals together and combines them for a summed output. For example, if you put in a 1V source and a 3V source, the output will be 4V. It's mainly used for CV, but it can be used to combine audio signals together.
A unity gain mixer is handy in several ways:
Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
Re-shaping two CV sources with a single envelope
Combining different wave shapes or LFOs to make crazy sounds.
Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.
Specifications:

SynthRotek AstroNoise Chiptune-Inspired Drum Module (eurorack noise/drum/oscillator module)
Cat: 852584 Rel: 20 Dec 21
A chiptune inspired drum machine!
Notes: The AstroNoise is a chiptune inspired drum machine! SynthRotek have added a Decay control and Trigger input to othe original circuit for that excellent lofi video game drum sound. The LEDs behind the sun shape follow the decay cycle, adding some style to your setup.
When the Trigger input is not patched, the module functions as a droning oscillator. The Rate, which uses a custom-made spaceship knob, controls the master frequency. The two LFOs and the LFO Level modulate the base frequency and allow you to make rhythms, video game motorcycle sounds and more. The LFOs can be turned on or off with the OSC ON/OFF switch.
The AstroNoise whets your appetite further by letting you choose between 3 different radical vintage tones. Slight changes in timbre can be made in the tones by flicking the switch back and forth, giving a wider palette to play with.* Shape the galactic frequencies with beats, lead lines and noise swashes!
Specifications:
Module width: 6HP
Module depth: 35mm
Power draw:
+12V: 130mA
-12V: 10mA
*Please note: The AstroNoise takes 5 seconds or so to warm up when turned on. If you don't hear any sound after a few seconds, toggle the tone switch back and forth a few times and it will come to life. It can also happen when toggling the tone switch after it is warmed up, but this has to do with the way the chips are interfacing with each other; just flip the switch to a different position and flip it back, and it will come back on!

SynthRotek DIRT Low Pass Filter/Effect Module (synth module)
Cat: 778171 Rel: 22 Jan 21
low-pass filter module
Notes: DIRT is our new 4HP low-pass filter / effect for the Eurorack modular synth platform.
The DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob, accessible from the front panel.
It's not a traditional filter; it's an effects module with filtering, ring mod effects, wave shaping and even outright brutal harmonic distortion.
DIRT likes to square things up a bit, so throw in a triangle, sawtooth, sine or other wave forms for different style effects. Even plugging a guitar (using an external amplification module) into the DIRT produces some great sounds and heavy distortion.
Controls:
- CUTOFF = Cutoff Frequency
- RESONANCE = Increase the Q!
- BIAS = Set the bias correctly or not, the choice is yours
Inputs/Outputs:
- Version 2.2, which as a buffered CV input jack. CUTOFF CV IN = Voltage range changes depending on where CUTOFF knob is positioned. External attenuation will be needed for fine modulation.
- AUDIO IN = Audio Input
- AUDIO OUT = Audio Output
Other info:
- PCB Dimensions: 4 x 1.5 inches
- 4HP
- Power consumption: >1mA

Notes: The Synthrotek DLY is a PT2399 bucket-brigade delay module. The PT2399 IC delivers warm and lush analog-sounding tones (the IC is partially digital). The DLY is similar in tone to our ECHO Eurorack module, but its features make it unique in its own right.
Unlike the ECHO which always has a wet signal (i.e. the output is always mixed in with the input), the DLY offers a true wet/dry Mix knob. When the Mix knob is fully counter-clockwise, you get a dry signal. When it is fully clockwise, you get a fully wet signal. This allows the user to plug this delay into effects loops. Also, the DLY allows for CV over Feedback and has an internal Feedback amount trimpot for precise adjustment.
Another added feature is the delay Rate range internal trimpot, which allows you to dial in the delay range of your choice. Turn the Rate knob all the way up to get the extreme, chaotic sounds of an over-clocked PT2399 chip.

Notes: The ECHO (formerly known as the EKO) is a compact voltage-controlled echo/delay comes in the very tidy size of 4HP and is certain to be one of the best bangs for your buck.
A very unique echo using the PT2399 IC featuring Voltage Controlled Rate. Manual controls for Rate, Feedback, and Mix. Beautiful and bizarre, CV modulation of the rate brings in ghostly pitch bent sounds to metallic reverbs. An effects module that everyone needs in their rig.
ECHO Rate CV accepts -5 / +5 voltages (although the negative range is almost -7)
ECHO Rate knob is setup to push the chip into extreme territory and will extend past the "useable" range of the PT2399 IC, meaning that once you turn the knob past 3 o'clock or so, the chip will stop operating and you'll only hear your dry signal.
Attenuation, attenuversion, or using an offset will greatly help when running voltages into the Rate CV input. This way, you can tailor the modulation as you see fit. You will absolutely get the most out of your ECHO by using modules that attenuate, invert or offset your signal.

Attenuation, attenuversion, or using an offset will greatly help when running voltages into the Rate CV input. This way, you can tailor the modulation as you see fit. You will absolutely get the most out of your ECHO by using modules that attenuate, invert or offset your signal.

SynthRotek Five Amp Blue Power Supply Module (power synth module)
Cat: 836844 Rel: 12 Jul 21
Power supply module - 4HP.
Notes: The Five Amp is a throwback to SynthRotek's original 5A Power Supply with some upgrades. It uses a quality 12V power brick for the +12V power regulation instead of a +12V converter. The plus side of doing it this way is that whatever amperage the -12V and +5V rails are not using can be used by the +12V rail, which always draws the most of the three.
Five Amp comes in three different power configurations. It is recommend that you select an option based upon your -12V rail draw. For a rule of thumb, Red (with red LEDs) will power a single row of 84 or 104HP, Green will power two rows of 104HP, and Blue will power three to four rows of 104HP.

SynthRotek Harben Octave Fuzz Distortion Module (distortion synth module)
Cat: 778294 Rel: 14 Mar 22
fuzz module
Notes: The Octave Fuzz is SynthRotek's take on the classic 70's SuperFuzz circuit, made into a Eurorack module, which has improved on some aspects of the original as well, including an increased output.
Two distinct voices like the original: switchable between scooped midrange and massive midrange bump.
Aggressive: It will sound massive and in-your-face like no other circuit can. This is for sonic explorers and heavy music only. In short, it's not useful for EVERYTHING, but the things it DOES do it excels at. Sounds especially killer for keyboard and bass sounds.
Tuned to give a subtle distorted waveform one octave up via wavefolding (see the video to view this on an oscilloscope). (Completed modules come pre-tuned; there are calibration instructions at the end of the assembly instructions for the kits)
This circuit has been optimized for Eurorack. You can find a guitar pedal version here.

Notes: The LPG is a West Coast Synthesis staple! The dual Low Pass Gate creates organic percussion timbres, paving the way for sonic exploration with a Buchla/Subotnick vibe.
The LPG has two low pass gates in one module. Its unique non-linear qualities emulate percussion timbres like congas, bongos, plucks, etc. The LPG is vactrol based, which creates natural-sounding decays. When the CV input is pinged by short/fast envelopes, it results in more organic sounds like bongos. The slide pot functions in two ways: when the the CV input is not patched, it attenuates/mixes the audio signal. When the CV jack is patched, it attenuates the output level and changes the timbre of the audio signal.
Each LPG channel can be used as a VCA. VCA mode bypasses the low pass filter and resonance and doesn't color the sound of your input audio. The vactrol gives the VCA a living, breathing, non-linear response.
A number of vactrols were tested for this module, and the pre-tested NSL-7053 yielded the most positive results. The NSL-7053 has a slower response and a more exponential response curve. The VTL5C4 has a slightly faster response and a more linear response curve. Vactrols have a lot of variance, so even if you use the same vactrols for both channels, each channel may sound a little different. But the LPG will work with a number of different types/brands, including dual vactrols. In fact, each channel can be built with a different set of vactrols. (Note: VTL5C3 and VTL5C3/2 vactrols are not recommended in the LPG.)

SynthRotek Quadrangle Quad Cascading Envelope Generator Module (envelope generator synth module)
Cat: 778303 Rel: 22 Jan 21
A quad cascading triggered envelope generator module with bipolar output attenuversion
Notes: The Quadrangle is quad cascading triggered envelope generator with bipolar output attenuversion. Each channel has voltage control over attack and decay/release, end of attack and end of cycle trigger outputs, and mode (AR, loop and AD). Each channel's EOC is normalled to the next gate input, resulting in interesting rhythmic opportunities. Channel 4 has a "stop" or "continuous looping" switch which allows either a "one shot" cascaded envelope or continuous cycling. The SUM output allows for longer and more dynamic bipolar envelopes, perfect for interesting modulation. Users also have voltage control over all of the attacks and decay/releases simultaneously when using the ALL A and ALL D/R input jacks. Massive function generation, modulation, rhythm and versatility sets the Quadrangle in a class of its own.
Features:
4 Cascading envelope generators
Attenuverters for each envelope output (dial in that secret sauce!)
Attack, Decay/Release and Loop modes per channel
From super fast ~2 mS (Audio Rate) envelopes, up to 8 second envelopes
CV over Attack and Decay/Release per channel
CV over ALL Attack and ALL Decay/Release
Bipolar Voltage SUM output of all envelopes
End of Attack & End of Cycle trigger outputs per channel

voltage generator module
Notes: This handy module is a feature rich random voltage generator that is shallow and super powerful. It outputs random voltages (similar to a sample and hold) in time with either its internal clock, or with an external clock you can patch in. An external clock will bypass the internal clock, and the CV jack over the clock, so your random voltages will always be in sync with whatever you patch in. With CV control over both the clock speed and the range of your output voltage, you could create anything from a wildly fluctuating blur of notes all the way to a slow, lilting tune. The RND can also be used as a clock source with it's clock out jack.
Note: due to the voltage drop of the LED in the slide pots, the Range LED wont light up unless the output voltage is above 2v.
Current Draw:
16mA @ +12v
0mA @ -12v
0mA @ +5v
Comes with:
Keyed power cable.
2.5 and 3.0mm rack screws.
Super cool sticker.

SynthRotek Roboto Robot Sounds Effector Module (digital/distortion/effect/pitch shifter synth module)
Cat: 778309 Rel: 22 Jan 21
CV controller/vocoder module
Notes: Need a vocoder, pitch shifter, speak-n-spell effect, vibrato, 8-bit modulator and a bit crusher sounding module all in a lo-fi heavily CV controllable package? Well surprise! we read your mind! The Roboto module is all these and more (and it has a neat Cylon looking graphic that lights up).
Vibrato toggles on and off. Works in either Robot mode or Pitch mode.
Robot and Vibrato CV inputs activate those modes (and deactivates in the case of vibrato) upon receiving a gate pulse. Gate pulses in these inputs are just like pushing their corresponding buttons. Expected transition is from 0V to +5V (and back to 0V), but it will handle any voltage within the power supply range without damaging the module. Transition between what is considered "off" and "on" is at approximately 2.3V.
Current Draw:
+12v @ 65mA
-12v @ 15mA
+5v @ 0mA
Depth: 34.5mm (1.36in)
Comes With:
Keyed Power Cable
2.5mm and 3mm rack screws

Notes: The S.MULT is a stereo buffered multiple. It has two channels. A signal plugged into Input 1 will be available from all 6 outputs. Break the chain by adding a second signal into input 2; signal 1 comes out 3 outputs and signal 2 is available at the remaining 3. What you put in, you get out!
Though it's a stereo mult, it can still be used for mono signals! With a mono input you can use both mono and stereo outputs at the same time, but will only get a signal on the left of the stereo outputs. You can plug mono or stereo patch cables into the outputs, they won't interfere with each other; the mono output will be the left of the input.
Specifications:
Module width: 3HP
Module depth: 30mm
Current draw:
+12V: 25mA
-12V: 25mA
